I got my powder from Walmart too, so it's prob the same brand. I do as the directions state with 100% success. What the directions do not say is the treatment of the cuttiNg prior to dipping. I take my cutting and put them in a glass of water right away. This helps to ensure it doesn't get an air bubble or dry out at all. While the cuts are still in the water, I then clip just the cut end off again for more added safety, scrape the outter skin (about an inch). Remove cutting from water right into powder, then into a potting mix. I like to have a hole in the soil ready to go as to not scrape off the powder, and fill in around the cutting. That's my method.
